The mirror itself is a large rectangular shape, but within it are smaller geometric shapes such as squares, triangles, and circles. These shapes are strategically placed to create the illusion of depth and perspective, making it seem as though there is a passage or doorway leading to another space. The reflection in the mirror adds to this illusion, creating a sense of infinity and mystery. The viewer is drawn into the mirror, trying to decipher where the real space ends and the reflected space begins. Overall, the Passage Hall Mirror is a captivating piece that plays with our perception of space and dimension. It challenges us to question what is real and what is a trick of the eye, making us rethink our understanding of the world around us.
